The invention proposes detection of man-in-the-middle intrusion between an entity (CL) and an access point (AP) of a network, in particular a network according to the IEEE-802.11 standard. To this end it proposes the following steps: a) reading frame bodies (FRA-i, . . . , FRA-i+3) transmitted between the entity and the access point, b) detecting frames (FRA-i, FRA-i+2) transmitted at respective different times but having identical frame bodies (fb), and c) triggering an alarm in the event of positive detection in the step b).
